Reflections on water: funerary practice and symbolism at the Bronze Age site of Xiaohe
Full text linkThe Bronze Age Xiaohe site allows for detailed archaeological analysis of funerary practices due to exceptional organic preservation in a hyperarid environment. Burials feature boat-shaped coffins, cattle skulls and hides, and grave markers resembling paddles and mooring posts. Material remains and environmental data indicate a deep cultural connection to water. The intentional inversion of burial elements suggests a conceptualization of an otherworld as a mirrored realm of the living. This article revisits early interpretations of Xiaohe burial practice and underscores the importance of considering symbols within broader cultural and environmental contexts, while providing interpretations rooted in data.1 Introduction 2 The Xiaohe cemetery 3 Sexual symbolism revisited 4 A contextualized symbolism of the Xiaohe burial assemblage 5 A mirror world 6 Conclusio
Skiftande minnen: Gravskick och kulturell interaktion i bronsålderns Kina : En studie av Xiaohe och Gumugou gravfälten i Tarimbäckenet
No full textThis study focuses on the burial practices in the Bronze Age Xiaohe-Gumugou cemeteries, north-west China, in order to understand how people constructed their social identities and delivered the social cognitions through generations. The Xiaohe-Gumugou cemeteries, as the main sites of the Xiaohe cultural horizon, have central roles for the understanding of the formation of the Bronze Age cultural groups and the cultural interactions between the west and the east in the Tarim Basin. However, current research is lacking in-depth examinations of the material culture of the cemeteries, and the contexts of the surrounding archaeological cultures in a timespan from Bronze Age to Iron Age. Through detailed comparisons of the construction of coffins and monuments, the dress of the dead, and the burial goods assemblages, this study provides an overview of the social structural development, from the Gumugou group’s heterogenous condition to the Xiaohe group’s homogeneous and mature state. Also, through relating to the results of biological and osteological analyses, and applying geographical analyses to the material, this study suggests that the early settlers in the Tarim Basin, the Xiaohe-Gumugou people have created their own social identities. Although the Xiaohe-Gumugou people might have migrated from southern Siberia or Central Asia, the archaeological material shows indications of their own typical features. When newcomers joined the society, the local burial customs were accepted and applied in a new cultural setting.Denna studie fokuserar på gravskick på gravfälten Xiaohe och Gumugou i nordvästra Kina, för att förstå hur människor konstruerade social identitet och överförde kulturella föreställningar mellan generationer. Xiaohe-Gumugou-gravfälten, som de viktigaste platserna i Xiaohe-kulturhorisonten, är centrala för förståelsen av bildandet av bronsålderns kulturgrupper och de kulturella växelverkningarna mellan väst och öst i Tarimbäckenet. Tidigare forskning saknar fördjupade undersökningar av gravfältens materiella kultur samt den historiska kontexten med de omgivande arkeologiska kulturerna under tidsperioden från bronsålder till järnålder. Genom detaljerade jämförelser av konstruktionen av kistor och monument samt de dödas klädsel och gravgåvor, ger denna studie en översikt över utvecklingen av sociala strukturer, från Gumugou-gruppens heterogena situation till Xiaohe-gruppens homogena och mogna tillstånd. Genom att relatera till resultaten från biologiska och osteologiska analyser och tillämpa geografiska analyser på materialet, tyder den här studien på att de tidiga bosättarna i Tarimbäckenet, Xiaohe-Gumugou-folket, har utvecklat egna sociala identiteter. Trots att Xiaohe-Gumugou-folket kan ha migrerat från södra Sibirien eller Centralasien visar det arkeologiska materialet indikationer på egna typiska egenskaper. När nykomlingar anslöt till samhället accepterades de lokala begravningssederna och tillämpades i ett nytt kulturellt sammanhang

Buried in sands: environmental analysis at the archaeological site of Xiaohe cemetery, Xinjiang, China.
No full textPalynomorphs extracted from the mud coffins and plant remains preserved at the archaeological site of Xiaohe Cemetery (Cal. 3980 to 3540 years BP) in Lop Nur Desert of Xinjiang, China were investigated for the reconstruction of the ancient environments at the site. The results demonstrate that the Xiaohe People lived at a well-developed oasis, which was surrounded by extensive desert. The vegetation in the oasis consisted of Populus, Phragmites, Typha and probably of Gramineae, while the desert surrounding the oasis had some common drought-resistant plants dominated by Ephedra, Tamarix, Artemisia and Chenopodiaceae. This present work provides the first data of the environmental background at this site for further archaeological investigation

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Analysis of ancient human mitochondrial DNA from the Xiaohe cemetery: insights into prehistoric population movements in the Tarim Basin, China
No full textBackground
The Tarim Basin in western China, known for its amazingly well-preserved mummies, has been for thousands of years an important crossroad between the eastern and western parts of Eurasia. Despite its key position in communications and migration, and highly diverse peoples, languages and cultures, its prehistory is poorly understood. To shed light on the origin of the populations of the Tarim Basin, we analysed mitochondrial DNA polymorphisms in human skeletal remains excavated from the Xiaohe cemetery, used by the local community between 4000 and 3500 years before present, and possibly representing some of the earliest settlers.
Results
Xiaohe people carried a wide variety of maternal lineages, including West Eurasian lineages H, K, U5, U7, U2e, T, R*, East Eurasian lineages B, C4, C5, D, G2a and Indian lineage M5.
Conclusion
Our results indicate that the people of the Tarim Basin had a diverse maternal ancestry, with origins in Europe, central/eastern Siberia and southern/western Asia. These findings, together with information on the cultural context of the Xiaohe cemetery, can be used to test contrasting hypotheses of route of settlement into the Tarim Basin
